MU'IOR FUEL No Drawin g.

To all whom it may concern:

Be it known that I, WILLIAM C. PERRY,

a citizen of the United States, residing at Kansas City, in the county of Jackson and State of Missouri, have invented certain new and useful Improvements in Motor Fuel;

and I do declare the following-to be a full,

clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to a combustion engine fuel and particularly to means for preventing the so-called knock apparent in the engine resulting from use of the present day gasoline. x

I have found that by introducing naphthylamin in the gasoline, the knock is not present.

This, I believe, is due to the fact that the boiling point of the gasoline is lowered, but from whatever cause, there is an appreciable absence of the so-called knock in the gaso- 'line when it is treated with naphthylamin.

Naphthylamin is not soluble in gasoline butit is soluble in benzol. In preparing the naphthylamin, I combine it with benzol in the proportions of one-to-one or about 50% each. The benzol and naphthylamin can be mixed either in liquid or vapor phase, the resultant product being a permanent solution of naphthylamin and benzol; that is, a solution which will 'not separate upon standing.

35 A suitable proportion of the solution is added to the gasoline. While naphthylamin is not soluble in gasoline but is soluble in.

benzol, the solution of benzol and naphthylamin is readily soluble in gasoline so that when the naphthylamin has beenfirst com= bined with benzol and then the resultant Application filed February 27, 1922., Seria1 No. 589,771.

product combined with gasoline, there is an effective solution which will not separate upon standing.

I prefer to combine the solution and gasoline in the proportions of from four to six per cent of the gasoline used although these proportions may be varied. When so combined, the so-called knock is not present.

In actual practice I have found the solution materially improves the gasoline, particularly in causing the absence of the so called knock and in some instances there is an appreciable increase, in mileage and power ofthe engine.

Benzol alone will reduce the liability of knocks in the gasoline but a relatively large proportion of benzol must be employed and since the amountof benzol available is limited, the amount of gasoline which can be treated would necessarily be limited. By combining naphthylamin with benzol to first provide a solution, a relativel small amount of the solution can be use in the 1 gasoline with equally good results. Therefore, a larger amount of gasoline can be treated than is possible when benzol alone is used.

What I claim and desire to secure by Letters lPatent is:

1. A motor fuel consisting of gasoline and naphthylamin in solution.

2. A motor fuel consisting of naphthylamin, benzol and gasoline. 3. A motor fuel consisting of a one-to-one 75 solution of naphthylamin and benzol combined with gasoline, the amount of gasoline preponderatin over the solution of naphthylamin and enzol.

In testimony whereof I aflix my signature.
